Editing Python script for Nautilus to work in Caja

[Minterbation]

Would it be possible to edit the source for Cover Thumbnailier http://projects.flogisoft.com/cover-thumbnailer/ to work with Caja? The install fails due to missing dependancies (Nautilus) but I don't think installing Nautilus to satisfy the dependancy is going to do any good. I want the thumbnails to generate while browsing folders via Caja. Anyone know if that is possible?
